Letters Patent No. 83,659, dated November 3, 1868.

RDVEIWENT IN BUTT-HING-E.

`-ei The Schedule referred to in these Lettera Patent au making part 0f the lla-m6- To all whom it may concern:

Be it known thatl, BENJAMIN CHARLES POLE, of Richmond, county of Henrico, State of Virginia, have invented a new and useful Improvement in Hinges; and I do hereby declare that the following is a full and exact description thcreo, reference being had to the accompanying drawings, and to the letters of reference marked thereon, in which-- Figure 1 represents sectionalview of hinge closed.

Figure 2 represents sectional view oi'hiuge opened.

Figure 3 represents perspective view ofhinge opened.

Figure 4 represents front view of plate O of hinge.

Figure 'represents hinged lever E and ro'd I detache-d.

Figure 6 represents top view of' bed-plate A.

In all, the same let-ters refer to the same parts.`

4A is the bed-p1ate.

.B, spring.

b, point at whichB is attached to A.

.C is the movable plate of hinge.

c c c, eyes in end of plate C, through which the connecting-rod H passes.

1), slot in plate C, in which plays E, the hinged lever.

F is the upper plate of hinge attached to door or lid.

Gil,i pivot connecting E and I, and on which E may wor H H, are connecting-rods, connecting plate O with F, and spring B with plate (l, respectively.'

I, rod connected with E by Gf.

K, top plate, corresponding to bed-plate A.

L is the side of case-to which door or vlid is hinged.

Mis the door or lid.

N, mortise in L.

O, channel for lever E and rod I.

P, channel in bed-plate A to receive plate G when closed.

The nature of my invention is a hinge in which the position of the line of revolution is changed, so that when the. door or lid is closed, the hinge will be coueealed from view, leaving a smooth, unbroken surface.

Io enable others skilled in the art to malte and use my invention, I will proceed to describe its construction4 and operation.

In the ixcd-side L oi case to whichthe door or lid is to be hinged, .I make a inortisc, N, oi suitable size and shape,in which I insert and securely fasten the bed-plate A, cast of metal, the shape of which is shown iuiig. 6. 0n the upper side of the mort-isc, I place the plate K, which should be made of steel, and is also fastened by screws tothe bed-plate A. To the underside of the bed-plate, in any convenient manner, is attached one end of the spring B, constructed of' any convenient shape or kind, the other end of which has an eye in it, through which passes the rod H, which connects it with hingep1ate C. Thehinge-plate C, the shape of which is shown in iig. fi, connected at ,lower end, as above stated, is similarly connected by rod H with the upper hinge-plate F, which is fastened, in any usual manner, to door or lid M, at a suitable distance orn its outer surface.' In the slot D of hinge C, plays the hinged lever E, which is hinged to the plates O and F, by rod H, which passes through eye c, (iigs. 4 and 5.) Through c of E, iig. 5, is a point which connects E with rod I, so that it may turn upon it. Rod I has a bend or head at the free end, so as to prevent it from escaping from a passage made for it between the bed- "plate A and top plate K, and thereby preventing the hinged leverE from being pulled from its proper posi tion, to act upon steel plate l( upon opening er closing. To show the manner in which the hinge operates, having been thus constructed, I suppose the to which it is applied open, as in and 3, the several parts of the hinge being of' such relative size that it will present the appearance therein exhibited. The lid or door is raised or opened in the usual manner, revolving on 'the rod H, which passes through c, until the upper plate of hinge Fcclnes in contact with hinged lever E, the lid or' door then being at rightan'gies with side L of case. Still pressing down, asusual in closin a lid, the platedescends, as indicated by red dotted line in iig. 2, and the hinge-lever E enters the opening between the bed-plate A and upper plate Il., sliding on the upper plate K, and pressing back rod I u the line of revolution c comes intopositiou, as nidi-cated in iig. 1, and the lid or door is shut, the hinge-plate C being in the channel i?, cut to receive it in bed-plate A, and the lower part oi" side L. The joint at c, on

which the upper hinge-plate F revolves, is 'thus below the surface of the side of cover L and lid er door M,

which come into close contact, and form an even sur face, entirely concealing the hinge from view.

To open the lid or door, proceed as usual., reversing the above operation.

The rod I, hy being forced against the ci' the bed-plate A and top plate K, prevents the hierI l. lever from escaping, and the lid or door M from tuning. or being pulled from its proper position.

I do not claiin any particular shape of thc parts herein described, nor the use of any particular kind of spring.

Y Having described the construction and operation of my improvementa'l will now state that What I claim as my invention, and desire to secure by Letters Patent, is as follows:

The bed-plate A, the spring B, the hinges-plate C with slot I), the hinged lever E, rod I, plate hinge plate F, all constructed, combined, and operating substantially in the manner and for the purpose herein set forth.

BENJAMIN C. PQLE.
